WHISTLE.

SPECIFICATION forming part of Letters Patent No. 414,188, dated November5, 1889.

Application filed March 2, 1889- Serial No. 301,766- (No model.)

To all whom it may concern.-

Be it known that I, WALTER I. BRIGHAM, of South Framingham, county ofMiddlesex, State of Massach nsetts, have invented an Improvement inVhistles, of which the following description, in connection with theaccompanying drawings, is a specification, like letters 011 the drawingsrepresenting like parts.

This invention has for its object to construct a whistle adapted to givetwo or more tones,'preferably of a different pitch.

In carrying out my invention I employ a plurality of sounding-tubesgrouped together to be moved in unison, and a single mouthpiece, themouth-piece being loosely connected with the tubes permitting movementone with relation to the other. The soundingtubes are provided with asuitable hand-piece, by which they may be rotated or moved to presentone or another in line with the mouthpiece, held stationary in themouth.

Figure 1 shows an end view of a whistle embodying this invention, andFig. 2 a side view of the whistle shown in Fig. l.

A plurality of tubes, as a, three beingherein shown, are soldered orotherwise secured together in a group, each tube having an opening atthe side, as at a, and containing within it suitable wooden or otherplugs of suitable shape to co-operate with the holes a to produce asound, and also containing within it other plugs of wood or othersuitable material, as indicated in dot-ted lines, to vary the pitch ofthe tone, all in suitable manner. The tubes a have secured to them atone end a plate Z), having holes through it arranged in alignment withthe tubes, there being three holes, as Z), herein shown, one for eachtube. The mouth-piece is herein shown as a flaring tube 0, having at itslower end a projection 0', through which passes a pin 0 which enters orpasses through the plate I), and serves as a swivel, connecting themouthpiece and plate. A hand-piece d is fixed to the plurality or groupof tubes, by which they may be moved in unison.

In operation the mouth-piece c is held sta t-ionary in the mouth, and bythe hand-piece (Z one or another tube a is brought into alignment withthe mouth-piece 0, so that by blowing into the said month-piece the toneof the particular sounding-tube then in alignment is produced. \Vhilethe mouth-piece is thus held, by turning, rotating, or reciprocating thehand-piece (Z, different tones, according to the pitch of the differentsounding-tubes, willbe produced in succession.

I do not desire to limit my invention to the particular number ofsounding-tubes employed, nor to the use of pitch-plugs to vary thepitch, nor to any particular construction by which the tubes may bemoved in unison, as man y changes may obviously suggest themselves to askilled mechanic which come within the scope of my invention.

I claim-- 1. A whistle comprising a plurality of sounding-tubes groupedtogether, and a plate 1), secured thereto at one end, and havingopenings therein in alignment with said tubes, combined with a singlemouthpiece having the projection c, and a pin passed through saidprojection and plate, whereby the mouthpiece is swiveled contiguously tothe group of sounding-tubes, substantially as described.

2. A whistle comprising a plurality of sounding-tubes grouped togetherand differently pitched, and a plate having openings therein inalignment with said tubes secured to one end thereof, combined with asingle movable mouth-piece swiveled to said plate, its inner end beingadjacent to said plate and adapted to be brought opposite any one ofsaid openings therein, substantially as described.

A whistle comprising, a plurality of sounding-tubes rigidly groupedtogether, and a hand-piece by which they may be moved in unison,combined with a mouthpiece loosely connected to the common longitudinalaxis of the said sounding-tubes, and adapted to form a continuouspassage with any one of said tubes, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WALTER I. BRIGIIAM.
